Crush the Biscoffs in the food processor to reach very fine crumbs.
2 cups crushed Biscoffs, Graham crackers, or Oreos will work
Melt the butter in the microwave, then add the sugar, and salt. Add this to the crushed Biscoffs and mix well.
½ cup Butter,, ¼ cup sugar, ¼ teaspoon Salt, 2 cups crushed Biscoffs, Graham crackers, or Oreos will work
Spread the above mixture in the prepared pan, and bring it to the sides. Be sure it is distributed evenly.
Bake the crust for 10 minutes, until you can smell its aroma. Bring it out of the oven and let cool. Bring the oven temperature down to 325°F.
How To Make The Key Lime Cheesecake Filling
Place the room temperature blocks of cream cheese in the food processor and blitz until fully smooth, and lump-free.
4 Blocks Cream cheese ,Full fat
Add the sour cream and blend well, then add the sugar, lime zest, and vanilla extract. Blend well.
1 tablespoon Clear vanilla extract, 1 cup Sour cream, Full fat, 1½ cups Sugar, 2 tablespoon Key lime zest, grated
Add the flour, and blend. The mixture should look very smooth and silky. Add the lime juice and mix.
2 tablespoon All-purpose flour, ¼ cup Key lime juice
Transfer the mixture to the bowl of the stand mixer, and set the paddle attachment. Add the eggs and the egg yolk, one at a time. It is very important not to incorporate any air into the mixture once the eggs are added.
3 Large eggs, 2 Egg yolks
Pour this mixture over the baked crust and place it in the water bath. SEE THE NOTE ON HOW TO MAKE THE WATER BATH. Pour boiling water into the bath.
Bake for one hour. Then gently shake the pan. The center should jiggle, and the side should look set and firmer.
Crack open the oven door, and leave the cheesecake in the oven for another hour. Then place it on the counter for half-hour. Place in the fridge for at least 3 hours or overnight.
